Title: One Pot Synthesis of Aziridine

Invention: The invention describes a way to produce chiral aziridine compounds in a one-pot reaction with no metal catalysts. This can offer a significantly reduced cost of production to manufacturers that utilize aziridine.

Background: Existing aziridine synthetic routes can seldom be done in a one step pathway. Furthermore, many syntheses require the uses of metal catalysts to achieve workable yield and still produce potential secondary products that are irrelevant to the use cases at hand.


The synthesis can be applied to creating biofoul resistant coatings for medical devices

Hardening agent for a variety of compounds


One pot synthetic reaction makes creating the compound relatively simple and cuts out costs that would have been associated with extra steps.

No metal components will also reduce costs from standard aziridine synthesis

Chiral output allows selective compounds to be developed and reduces waste and secondary products
